[0025] It should be noted that, due to the obvious deficiencies in the existing cutting equipment in fixing steel pipes, it is impossible to stably fix steel pipes of different sizes, and displacement is prone to occur during the processing, which significantly affects the cutting accuracy. At the same time, these devices are highly dependent on manual operation during the feeding process, which undoubtedly increases the risk of operation and may lead to the occurrence of safety accidents. This solution realizes the precise fixation of the steel pipe body and one of the ends by setting a positioning mechanism, ensuring that no displacement will occur during the subsequent cutting process; this positioning method significantly improves the accuracy and work efficiency of cutting, and reduces the risk and error of operation; in addition, the two clamping plates 205 with adjustable spacing can be used for processing and fixing steel pipes of different sizes; this design takes into account the processing requirements of steel pipes of different specifications, and significantly improves the scope of use and flexibility of the device; whether it is large or small steel pipes, this device can easily cope with it and meet a variety of different cutting requirements; by setting an automatically movable assembly seat 203, this device realizes automatic feeding of steel pipes, further improving work efficiency and safety; the automatic movement function of the assembly seat 203 reduces the time of manual adjustment and calibration, so that the steel pipe can be quickly and accurately fed into the cutting area.

[0039] Working principle: When the device is used, the end of the steel pipe to be cut is passed through the through hole 202 of the limit table 201 to support the end, and then the pipe body of the steel pipe is placed on the assembly seat 203, and the steel pipe is fixed between the two clamping plates 205 by the clamping force of the hydraulic rod 204. The clamping force of the hydraulic rod 204 is stable, which can ensure that the steel pipe will not move or vibrate during the cutting process, thereby reducing the operation risk. A rubber pad 9 is arranged on the inner side of the clamping plate 205; the rubber pad 9 can be used between the steel pipe and the clamping plate 205. The plates 205 act as buffers to prevent the steel pipe from deformation and damage, thereby ensuring the processing quality, and can increase the clamping area of ​​the steel pipe, thereby improving the clamping force, making the clamping more secure, less prone to loosening and offset, and meeting the processing requirements of the steel pipe; the two clamping plates 205 with adjustable spacing can be used for processing and fixing steel pipes of different diameters, thereby improving their scope of use and flexibility; through the coordinated use of the limit table 201 and the assembly seat 203, the position of the steel pipe can be quickly and accurately determined, reducing the time for adjustment and calibration;

[0040] Then, the vertical plate 6 is slid to align the push plate 8 with the end of the steel pipe, and the electric push rod 7 drives the push plate 8 to contact the end of the steel pipe, cooperating with the clamping plate 205 to prevent it from rotating during the cutting process, thereby further improving the stability of the steel pipe clamping;

[0041] The thrust of the driving cylinder 302 makes the cutting knife 304 contact with the steel pipe body and exerts pressure, and at the same time, the servo motor 305 drives the cutting knife 304 to rotate at high speed to perform cutting; the driving cylinder 302 can also be used to adjust the distance between the cutting knife 304 and the steel pipe body to adapt to steel pipes of different diameters, ensuring the accuracy and efficiency of cutting;

[0042] Driven by the motor of the screw slide 4, the screw slide 4 can accurately control the forward and backward movement of the assembly seat 203; the movement of the assembly seat 203 drives the steel pipe to move synchronously, realizing the automatic feeding process of the steel pipe, and moving the end of the uncut steel pipe into the through hole 202 for continuous processing; this design simplifies the operation process and improves work efficiency and safety.
